What Is a Flexible Gas Line?
A flexible gas line is an improvement over the traditionally-used iron pipes that were used to supply gas to homes for years. The key difference is in the material used, and it has been proven to be a safe and efficient alternative for installing residential gas lines. Advantages to using these flexible gas lines include less labor and the ability to add future gas lines.
Rather than heavy iron, flexible gas lines are made from corrugated stainless steel tubing (CSST). When used in homes, they supply natural gas to stoves, furnaces, gas fireplaces and many other appliances. They are permitted by all state and local building codes and have become more popular with builders in recent years.
Flexible gas lines made of CCST do not require the labor-intensive cutting and threading that iron pipes do. They are installed in much the same method as electrical lines, stretched between 2 connectors and cut to the needed length. These gas lines also do not need the large number of T-connections at 90 degrees every time they need to change directions. The CSST can simply be bent in any direction necessary. This flexibility has shown to reduce the frequency and number of gas leaks, making it a safer alternative to iron pipes.
When deciding between a ventless propane fireplace or a vented model, there are a few things you should know about the efficiency and operating look of both units. Each type requires a main source gas line provided by your local gas company.
Vented Propane Fireplace
This unit will give you a realistic-looking fireplace flame. The vented style uses a flue pipe or a standard masonry chimney. As long as the damper is open, it does not require carbon monoxide monitoring. The fumes or smells exit the home just like a wood burning fireplace. These units require slightly more gas than a ventless fireplace.
Ventless Propane Fireplace
The aesthetics produced by a ventless fireplace are not as realistic as a vented fireplace will produce. Ventless burning gas produces more moisture in your home. Some cities do not permit ventless fireplaces, check your local codes. While it will be necessary to leave a window or door cracked open while using the ventless propane fireplace, the heat that is produced is much more efficient than a ventless propane fireplace. It will use less gas and release fewer pollutants into the air.
